Boeing projects a $4.9 trillion commercial aviation support and services market over the next two decades, alongside demand for more than 2.4 million new aviation personnel through 2045. The company published the figures in its Services Market Outlook in July 2026.

Fleet growth underpins the services projection. The global commercial fleet is expected to exceed 50,000 aircraft by 2045, requiring approximately 44,000 new passenger jet and freighter deliveries across the period. Replacement demand is rising as mature and transitioning markets renew their fleets, and Boeing expects that fewer than 10 percent of previous-generation aircraft will remain in service by 2045.

Traffic assumptions drive both figures. Passenger traffic is forecast to grow 4 percent annually, which doubles global air traffic between 2026 and 2045. Air cargo traffic is projected to expand about 3.7 percent annually through 2045, a rate that outpaces both trade growth and general economic growth.

Workforce demand splits along a clear line. Two-thirds of the 2.4 million personnel requirement covers replacement of retiring staff, while one-third supports fleet expansion. That ratio places the majority of the hiring burden on succession rather than growth, a distinction that affects how quickly training pipelines must produce certificated technicians.

Boeing segments the services market into four functions: maintenance, repair, overhaul and modifications; parts and supply chain; training and professional services; and digital solutions and analytics.
